Stormwater Management Program

The City of Hendersonville is currently operating under the Phase II National Pollutant Discharge Elimination System (NPDES) General Permit for Discharges from Small MS4s (Permit TNS075353). The permit allows the municipality to discharge stormwater runoff from municipal drainage systems into the waters of the state. The permit requires that the City of Hendersonville develop and implement specific programs and best management practices to protect water quality through a Stormwater Management Program/Plan (SWMP). The Hendersonville SWMP is required to address stormwater quality through six minimum control measures.

  1. Public Education and Outreach on Stormwater Impacts
  2. Public Involvement/Participation
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Stormwater Runoff Control
  5. Post-Construction/Permanent Stormwater Management in New Development and Redevelopment
  6. Pollution Prevention/Good Housekeeping for Municipal Facilities

Additional Permit Requirements

Analytical and Non-Analytical Monitoring- The City works with environmental consultants to satisfy analytical and non-analytical monitoring requirements.  Public notice is provided prior to the start of monitoring activities.  Results of monitoring activities are included in the annual MS4 report.
